With any large group of people, it's inevitable that someone won't get the memo, and in the case of the Grammys, there literally was a memo, issued by CBS and admonishing Grammy attendees from baring too much skin, the "bare fleshy under curves of the buttocks and buttock crack" and "puffy" bare skin exposure. Among those who obviously didn't get the memo: Jennifer Lopez, Skylar Grey and Kelly Rowland. Actually, J.Lo got the memo, as she told E! "They didn't say anything about leg."

Taylor Swift opened the show with a three-ring circus of "Alice in Wonderland" imagery, and she performed her hit "We are Never Ever Getting Back Together." Swift once again demonstrated her show business shrewdness, filling the stage with so many stilt walkers, clowns, flame dancers and human marionettes that it's likely some failed to notice that she continues to sing poorly live.
